Application filed January 13, 1911. Serial No. 602,402.

To all whom it may concern:

Be it known that l, TnoMAs Gone, a citizen of the United States, and aresident of the borough of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful improve ments in Cables,of which the following is a specification.

The invention relates particularly to cables for drilling wells.

Tn drilling work, a long cable is employed and this cable is raised andlowered by a rocking beam or similar contrivance, so that the toolcarried on the end of the cable, will, by its impact, cut its waythrough the material being bored. Twisted strand cables are usuallyemployed for this purpose. One serious objection to these twisted strandcables is that when a strand breaks, or when the rope itself breaks, asquite frequently happens, the broken strand or strands will fray out orunravel, and usually choke up the hole.

My invention aims to overcome this very serious objection.

Accordingly my invention consists preferably of a stranded cable inwhich the strands are braided together and so interlocked that eventhough a strand should be broken, the broken ends will be still heldinterlocked and so prevented from fraying or unraveling. And on accountof this interlocking or interweaving of the strands, should the ropebreak, the strands will still be held and prevented from becoming Thestrands are made up of suitable yarn such as hemp, manila, or the like,and each strand is preferably provided with a suitable core. This coremay be in the form of a wire, or of a plurality of wires united in someway, as by twisting, and the core may in some cases be surrounded by afibrous wrapping such as marlin;

In its preferred form the cable is braided so as to be angular incross-seotion-usually square. This is a decided advantage, as greaterwearing surface is provided than in the usual r und cable.

Various other features of the invention Wlll appear as the specificationproceeds.

In the accompanying drawings are illus-v parting from the spirit andscope of the invention. I

In the drawings: Figure l is a view in elevation of a portion of a ropeor cable embodying my invention. Fig. 2 is a crosssectional view of thesame. Fig. 3 is a like view of another form of the invention, and Fig. iis a broken elevation of the rope shown in Fig. 3.

Like reference characters refer to like parts throughout the severalviews.

[is clearly shown in the various views, the strands l are braided orplaited together into a homogeneous cable 2. The number of strands mayof course 'vary to suit different conditions and requirements, but theyare preferably laid together so as to interlock and form a ropesubstantially square in cross section, as seen in Fig. 2.

The individual strands are preferably made up of twisted yarn, and arepreferably each provided with a core. This core may and preferably doesconsist of a plurality of twisted wires 3 over which the covering ofyarn 4:, is placed, preferably by twisting. Immediately surrounding thewire core there may be placed a spiral wrapping 5 of fibrous material,such as marlin.

The individual strands or the cable itself may be treated to render itwaterproof or to give it other desired qualities.

My invention is capable of being made up into flat rope with greatadvantage for a much greater wearing surface is thereby provided than inthe ordinary style of flat rope which is made up of a plurality of roundropes. Figs. 3 and 4 illustrate a flat rope made up in accordance withmy invention, the same consistin of a plurality of square braided ropeslaid together side by side, and secured so as by means of stitcln ing 6.

What is claimed, is: I of New York and State of New York this b A doableconilprising a ilurality of strands 12th day of January A. D. 1911.
